Chapter 2 Checking before OS Installation
2.3.2 Notes on Configuring RAID
Take the following notes when you configure a RAID system.
■ Hardware Configuration
• Only internal hard disk units can be used.
• Be sure to use hard disk units of the same model and with the same capacity.
• Two hard disk units can be configured for installation. An array configuration cannot be established
with only one unit.
• The only RAID level configurable with this server is RAID1.
When the OS is installed using ServerStart, only one RAID card can be installed. If you need more
cards, install them after OS installation.
■ Checking before OS Installation
• When a RAID-configured disk is used
Used hard disk units can contain unnecessary partition or array configuration information that can
cause unforeseeable problems.
Before connecting a used hard disk unit to this server, connect it to a different system and perform
low-level formatting on the hard disk unit.For the low-level formatting procedure, refer to the manual
supplied with the system used for formatting.When performing low-level formatting on a hard disk
unit used on this server, refer to "8.3.8 Formatting hard disks physically" (
pg.244).
• Number of disk units
If only one hard disk unit is set, installation with ServerStart causes an error and will be aborted.Be
sure to configure two units.
2.3.3 Notes on a Multiple LAN Adapter Configuration
Using the OS installation wizard of ServerStart, you can configure multiple LAN adapters (network
adapters) on the system. However, there are the following limitations.
● Adapter Numbers
To configure multiple LAN cards, select the adapter numbers in order of Adapter 1 and Adapter 2, and
enter settings for each adapter. Note that the order of adapter numbers is not necessarily the same as the
order of slots for the installed LAN adapters. This means that the setting for Adapter 1 is not always
applied to the onboard LAN. After installing the OS, check the LAN adapters to make sure that they are
configured as intended.
